摘要
Information of crop phenological stages is essential for evaluating crop productivity and crop management. We used MODIS EVI time-series to monitoring winter-wheat phenology in North China. The phenological estimations from MODIS EVI measurements were compared with situ data. Results indicate that winter-wheat phenological stages derived from MODIS EVI time series data is feasible. The spatial pattern of winter-wheat shows obvious latitudinal trends in this region. Green up, tassel, and maturity onset dates in more southern zone begin earlier progressively than the northern zone.
